Domains are very good investment.That's why I have to buy some domains that I can think off.Im anticipating this domain will cost a much higher price in the future.Currently I own 30 domains.All registered at Godaddy.com
I currently only own 15 domains at GoDaddy. I used to own a lot more but sold them all on for a nice profit. I often purchase domains and sell them on for a profit. That's why i rarely have more than 20 domains at any one time.
I currently own nearly 45 domain names which 90% of them I dont seem to be using at all, I guess with more people working their way into the IT market and moving to an e-business scenerio getting the names first is all that matters.
I have 18 domains with several registrars. Actually these are all for my own use with email, blogs, photo album etc. The registration fee is so cheap nowadays I think people will have many too.
